Hi. Lately I ve been getting weird sensations (temporary) of weakness in arms and legs, shakiness, burning hunger, and anxiety. Also, my vision will go darker. I can tell that to feel better I have to eat something, usually something specific (like a sever craving). In the past it s mostly been cinnamon rolls and bananas, but not always. These symptoms come on quickly and I can tell when it starts to build. Any idea what this is or is it just nothing?
